By the reaction of with the thiols RSH (R=But, C6H3Me2-2,6 or C6F5) amorphous gold(I) thiolates Au(SR) were obtained.With 2,6-dimethylbenzenethiolate under CO at atmospheric pressure in CH2Cl2 as solvent, gold metal and RSSR were formed, while with H2S amorphous Au2S was the product.The reaction of with t> in 1:1 ratio yielded t> 1 and 2 (15-crown-5=1,4,7,10,13-pentaoxacyclopentadecane).The crystal structure of 1 revealed that the anionic part contains three AuCl groups co-ordinated to the ButS- ligand forming a tetrahedral arrangement around the sulfur.The - anions in 2 are co-ordinated through the chlorine atoms to two + cations; thus, the sodium cation has a distorted pentagonal-pyramidal co-ordination to five oxygen atoms of the crown ether with the axial position occupied by the chlorine atoms of the AuCl2- anion.The reaction of with t> in 3:1 molar ratio afforded the mixed-valence AuI-AuIII complexes 42(Au4Cl6S2> 3 and 2 4.Their crystal structures revealed that in the 2- anion two AuCl2 units are connected by the sulfur atoms of two SAuCl groups forming a centrosymmetric planar Cl2Au(μ-S)2AuCl2 skeleton.The structure of 3 also contains linear - anions.
